Creating a loose man.

If for example we have a loose player in the centre on his own (whether on the forward line or backline) when we have the ball, a position player HFF , HBF or a Winger moves towards the loose player taking his opponent with him to that position (creating space) this will allow the loose player to move into space created and be used.

In what other situations do you think provides the option of creating a loose man? Is it part of your teams strategies?
